UnderGlow™ pairs 630 nm red light with a licorice-infused brightening cream to calm, smooth, and visibly even tone on underarms—plus elbows, knees & bikini line. Through photobiomodulation, red light boosts cellular energy and fibroblast activity to promote natural turnover and a firmer look, while licorice helps interrupt excess-pigment pathways—so dark patches gradually fade and skin looks more even and radiant. Optional heat, micro-vibration, and low EMS enhance comfort, microcirculation, and consistency. Hydroquinone- & kojic-free.

Stop Hiding, Start Glowing: Reveal Radiant Underarms in Just 2 Weeks
Serums alone can’t beat friction, inflammation, and lax texture—so why keep fighting your underarms?
Here’s how UnderGlow™’s Red-Light Therapy + Brightening Cream team up to transform your underarms:
Red Light Therapy
630 nm red light increases cellular energy (photobiomodulation) and supports fibroblast activity—promoting natural turnover and a firmer, smoother look while calming the irritation that drives pigment buildup. Optional heat and micro-vibration boost comfort and micro-circulation, and low EMS aids fluid movement for a subtly toned feel.
Brightening Cream
Licorice (dipotassium glycyrrhizate) helps interrupt excess-pigment pathways as glycerin hydrates and vitamin E softens—reducing friction and supporting a calmer barrier. Its silky slip also conducts EMS for gentle treatments. Hydroquinone- & kojic-free.
Effortless 4-Step Underarm Transformation
Step 1: Start with fresh, dry skin. Gently cleanse your underarm area.
Step 2: Apply Underarm Whitening Serum onto your fingertips and massage evenly into both underarms.
Step 3: Turn on your UnderGlow™ Red-Light Therapy device and select your preferred intensity. Hold the light just above your treated underarms, moving in slow circles for 5 minutes per side.
Step 4: Use daily for 2–3 weeks to unlock your smoothest, brightest underarms yet.

Frequently Asked Questions
How do I use UnderGlow™?
1. Prep - Clean & dry skin.
2. Cream – Apply a thin layer of the Licorice Brightening Cream.
3. Activate – Power on; start with Red + Heat (add Vibration, then EMS L1 as comfy).
4. Glide – Hold the head ~½″ from skin and keep moving in slow, overlapping circles for 5–6 min per side (underarms).
5. Finish – Power off, wipe the head, let the cream absorb. Deodorant/moisturizer last.
How long until I see results?
Most users notice a calmer feel in 1–3 days and more even-looking tone in ~7–14 days with daily use. Texture continues to smooth over 3–6 weeks.
Which mode should I pick?
- Every session: 630 nm Red Light (core).
- Post-shave calm: Red + Heat (add Vibration if you like).
- Tone assist: Red + EMS L1 (cream helps conduct).
- Texture focus (elbows/knees): Red + Heat, (+ Vibration optional).Tip: Keep EMS low/off on freshly shaved or tender skin.
Does the red light damage skin?
No. UnderGlow™ uses non-UV 630 nm red light (photobiomodulation). It’s non-ablative and safe when used as directed. The Heat mode is separate and kept to a comfortable ~38–45 °C.
How often should I use it?
For fastest brightening, use once daily for 2–3 weeks, then 3–4×/week to maintain.
Can I use it after shaving, waxing, or laser?
- Shaving: same day is fine—start with Red + Heat only for 24 h; add EMS later.
- Waxing/Laser: wait 24–48 h or until skin feels calm; begin with Red + Heat.
Can it help with ingrowns?
Not a medical treatment, but by calming inflammation, improving comfort/micro-circulation, and pairing with a soothing cream, UnderGlow™ helps create conditions that mean fewer bumps/ingrowns over time.
Is it suitable for all skin types and tones?
Yes—designed for normal, oily, dry, and sensitive skin and all Fitzpatrick tones. Because the cream contains fragrance and lanolin, patch-test if you’re reactive.
What about other skincare—retinoids, acids, deodorant?
Use the Brightening Cream first, UnderGlow™ second, then apply deodorant or moisturizer. Save strong exfoliants/retinoids for off-days (not the same session).
Can I use it on the bikini line?
Yes—on external skin only (not mucosa). Keep Heat low, EMS low/off if tender, and use 3–5 min per side.
I don’t feel the EMS—what should I do?
EMS needs moist skin and good contact. Apply a thin layer of cream, keep the head flush/close, hold the handle to complete the circuit, then increase from L1 as comfortable.
Is it waterproof? How do I clean it?
Not waterproof. Unplug, then wipe the head/body with a soft cloth or paper towel. Do not rinse.
Who should avoid EMS?
Skip EMS if you have a pacemaker/implanted electronic device, a seizure disorder, active skin infections, or if your clinician advises against it. If pregnant, consult your provider (you can still use Red + Heat/Vibration with approval).
Will it bleach my natural skin color?
No—UnderGlow™ aims to even the look of tone caused by friction and irritation. It’s hydroquinone- & kojic-free and uses a licorice-infused cream to support a calmer, more uniform appearance.
